1 Claim. (Cl. 275-3) This invention relates to improvements in manurespreaders and breakers for agricultural trailers.

The manure is transported in a trailer having an apron chain t'eed alongthe bottom to remove the manure towards the rear. The manure is liftedfrom the trailer by a plurality of rotary spreaders which break up themanure and distribute it over the ground rearwardly ot' the trailer.

According to the invention rotary spreaders in the form of cylindersarranged transversely of the trailer are constructed of a plurality ofspaced bars arranged spirally or the cylinder, a series or U-shapedteeth being bolted to each bar.

the invention will be described with reference to the accompanyingdrawings:

Fig. 1 is a front elevation of the top and bottom spreaders showing thebearings and driving pinion in section on line 11 of Fig. 3;

Hg. 2 is a part elevation of the discs showing the spreaders mountedthereon;

Pig. 3 is a side elevation of part of the trailer showing the drive forthe spreaders.

The manure is lifted from an apron travelling along the bottom of avehicle or trailer D by a lower rotary spreader A and broken up ordisintegrated by traversing between the spreader A and a second upperrotary spreader B from which it is transferred to a rotary distributor Carranged at the tail end of the trailer from which it is distributedover the ground rearwardly of the tra er.

Each spreader A, B comprises a plurality of bars, 1, 2 preferably ofangle section mounted on discs 3, 4 to form open cylinders with the bar1, 2 extending spirally between the discs 3 and 4. Three or other numberof discs 3 and 4 may be provided, each disc being formed with notches 3and 4 around their peripheries, one edge of each notch 3 or 4 being bentat an angle corresponding to the spiral angle of the bars 1 and 2 toform flanges through which the bars 1 and 2 respectively may be boltedthereto. Ribs 5 are provided on the discs 3 for stiffening purposes. Thediscs 3 and 4 are supported on hollow shafts 6 and 7 for each spreader Aand B. A plurality of teeth 8 are bolted to the bars 1 and 2 each tooth8 being of U shape to provide two prongs 9, the ends of which arepointed to break up the straw in the manure. The prongs 9 may beelliptical or bottle shaped. The teeth 8 on the bars 1 and 2 may bestaggered in relation to those on adjacent bars.

The cylindrical spreaders A and B rotate on stationary spindles 10, 11which are mounted on the trailer D, and pass through the shafts 6 and 7,respectively. The

States Patent 0 2,694,579 Patented Nov. 16, 1954 spindles 10, 11 for theupper and lower spreaders A and B are mounted on roller bearings 12 and12 at each end carried in bearing housings 13, 13 capable of rotatingabout the spindles 10 or 11, a resilient coupling 14, 14* being providedbetween the end discs 3, 4 and the housings 13, 13 The resilientcouplings 14, 14 serve the two purposes of absorbing the vibration andshock loads and of acting as self aligning bearings. A sprocket wheel 15is coupled by dogs 16 to the bearing housing 13 at one side of the upperspreader B, the sprocket wheel 15 rotating on roller bearings 17 on thespindle 11. The lower spreader A is driven through a sprocket wheel 18engaging the lower bearing housing 13. The sprocket 18 is formed with aboss 19 bolted to a second sprocket wheel 20. The sprocket 18 and boss19 rotate on roller bearings 21 on the spindle 10.

A driving chain 22 passes over the sprocket 18 on the lower spreader A,over a jockey sprocket 23 and over a sprocket 24 driven by a gear wheel25 on a driving spindle 26. The upper spreader B is driven at adifierent speed from the lower spreader by a chain 27 passing over thesprocket 15 on the upper spreader B, over the sprocket 20 on the lowerspreader A over a jockey sprocket 28 and over a sprocket 29 driving thedistributor C.

The shaft 6 may be supported at one side of the trailer D on a bracket30 bolted thereto. The shaft 7 may be supported on a bracket 31 alsobolted to the trailer D at one side.

I claim:

A manure spreader for agricultural trailers having spaced side walls,comprising in combination, two spaced hollow shafts; heating meanssecured to the end portions of said shafts; two parallel spaced spindlessecured to the side walls of the trailer so as to extend transverselyacross the trailer, said spindles passing through said hollow shafts andsupporting said bearing means so that said hollow shafts are rotatablymounted on said spindles; two sets of spaced discs each set of discssecured to one of said spaced shafts, each disc being formed along theperimeter thereof with transversely projecting spaced portions havingradially extending faces; two sets of transversely extending bars havingan L-shaped cross-section, said bars being secured with one leg thereofto said radially extending faces of said projecting disc portions andbeing arranged in spiral relation to the axis of rotation of therespective hollow shaft; a plurality of spaced U-shaped teeth secured tothe other leg of each of said bars so as to project in a radialdirection; driving sprocket wheels coupled to said bearing means; andchain means for driving said sprocket wheels.
